Coil component and display device including the same

Abstract

There are provided a coil component capable of easily mounting in a narrow mounting space, and a display device including the same. The coil component including: a bobbin including a cylindrical body part having a plurality of coils wound on an outer peripheral surface thereof, flange parts formed at both ends of the body part, and at least one or more core support parts protruded from outer surfaces of the flange parts; and a core coupled to the bobbin and seated on and fixed to the core support part.

What is claimed is: 
     
         1 . A coil component, comprising:
 a bobbin including a cylindrical body part having a plurality of coils wound on an outer peripheral surface thereof, flange parts formed at both ends of the body part, and at least one or more core support parts protruded from outer surfaces of the flange parts; and   a core coupled to the bobbin and seated on and fixed to the core support part.   
     
     
         2 . The coil component of  claim 1 , wherein the core includes:
 a first leg inserted into a through-hole of the body part;   a second leg disposed outside the body part; and   a connection part connecting the first leg and the second leg.   
     
     
         3 . The coil component of  claim 2 , wherein the second leg is formed to have a width wider than that of the first leg. 
     
     
         4 . The coil component of  claim 3 , wherein the connection part has a width increased in a direction toward the second leg. 
     
     
         5 . The coil component of  claim 2 , wherein the second leg is disposed above an upper portion of the bobbin. 
     
     
         6 . The coil component of  claim 5 , wherein the second leg is disposed to entirely cover the upper portion of the bobbin. 
     
     
         7 . The coil component of  claim 2 , wherein the second leg has a concave inner surface, corresponding to a shape of the bobbin facing the second leg. 
     
     
         8 . The coil component of  claim 1 , wherein the core support parts are respectively disposed on both sides of the body part based on the body part. 
     
     
         9 . The coil component of  claim 8 , wherein the core support parts include a supporting surface formed to be inclined to contact and support the core. 
     
     
         10 . The coil component of  claim 8 , wherein the core support parts guide the core to be disposed at a center of the body part using gravity. 
     
     
         11 . The coil component of  claim 8 , wherein the core support parts support a portion of the core exposed outwardly of the body part. 
     
     
         12 . The coil component of  claim 1 , wherein the body part has an oval cross-sectional shape elongated in a vertical direction. 
     
     
         13 . The coil component of  claim 1 , wherein the bobbin includes a terminal connection part extended from the flange part. 
     
     
         14 . The coil component of  claim 1 , wherein the core is configured as a pair of U-shaped cores. 
     
     
         15 . The coil component of  claim 1 , wherein the core is coupled to the bobbin so as to be spaced apart from an inner surface of the cylindrical body part. 
     
     
         16 . The coil component of  claim 1 , wherein the bobbin includes at least one or more partition walls partitioning a space in which the coil is wound into a plurality of spaces in a length direction of the body part. 
     
     
         17 . A coil component, comprising:
 a bobbin including a cylindrical body part having a plurality of coils wound on an outer peripheral surface thereof; and   a core having a first leg inserted into the body part,   wherein the first leg is disposed to be spaced apart from an inner surface of the body part.   
     
     
         18 . A coil component, comprising:
 a core; and   a bobbin including a cylindrical body part having a plurality of coils wound on an outer peripheral surface thereof and having the core inserted thereinto and a core support part supporting the core outside the body part,   wherein a movement of the core is fixed in a horizontal direction and in a downward direction by the core support part.   
     
     
         19 . A display device, comprising:
 a power supply having the at least one coil component of  claim 1  mounted on a substrate; and   a display panel receiving power from the power supply.
